Be it known that -I, JAMES GRAY, ot' Newarlr in the county of Essex, and State of New Jersey, have invented anew and improved Sad-Iron; and I do hereby declare that the following is a full, clear, and exact description thereof, whichwill enable others'skilled in the art to make and use the same, reference being; bad to the accompanying drawings, forming part'of this specification.

Figure lrepres ents a longitudinal vertical section of my improved sad-iron.

' Figu're2 is a vertical transverse section of the same. 1

Figure 3 is a plan or top view of the same, showing the cover turned back and the iron open.

Similar letters of reference indicate corresponding parts.

This invention relates to a new self-heating sad-iron, which is soarranged that the cover of the ironwill remain cool, and so that the draught can at all times be regulated at will. d

The invention consists in the use of a perforated bed, fixed stationary in the lower part of the hollow sadiron, its interior communicating with the outside airlby a hole in the side of the iron; the hole being arranged high enough to prevent the falling out of ashes. f I

4 The invention also consists in the useofa hinged or removable cover, which is made of two plates, having an air-space between them for the circulation of fresh air. 1 V r The said cover is thereby always kept cool, and with, it'the handle of the sad-iron.

The invention consists'finally in the use of the damper, arranged below the lower:- entrance of the smoke- V pipe, the said damper being operated by a pin fittingthrough a slot in theupper plate of the cover. The draught can thereby be completely regulated. .A represents a hollow sad-iron, of suitable or ordinary form and material. Above its bottom, nearits rear or broad end, is. arranged a perforated cap, B, which is firmly secured in the iron, and which acts as a grate for the fuel. 7 I u ,7 An air-hole, a, is madejn the back orside plates of the iron to' communicate with the'interior of, the cap, the said air-hole 01' holes being arranged high enough above the bottom of the iron to prevent; the falling out of ashes. l v p i The air entering through the hole a into the cap B, is fed to the fire through the holes in the cap, and sup: plies the same with the requisiteamount of oxygen. g I

The products ofcombustion escape through a smoke-pipe, C, which is fixed on the cover of the iron.

The-whole or part of the cover D of the sad-iron'is hinged to or made removable from the hody of the iron,

and consists of two plates, 6 and a, one arranged above the other, so as to leave an air-space, d, between the same, as is clearly shown in figs. 1 and 2. l

This air-space 01 does, when the whole cover fits upon the iron, allow the direet circulation of the air below the upper plate I; of the cover, thereby keepingthe said plate at all times cool, and with it thehandle E of the iron, which is fixed to a standard or standards, F, projecting from the cover. d I

If the cover is so arranged that only its upper plate 6 fits upon and rests on the edges of the iron, so, that the air-space is surrounded by the walls-of the iron, then the said walls have to be perforated, as shown in fig.

1, to allow the circulation of air through the said space d for the aforesaid purpose.

Between the plates 6 and c is arranged a sliding plate, G, (see fig. 3,) which is provided with a projecting pin, e, projecting upward through a slot inthe upper plate 6. This plate G can be moved, so as to close the lower end of the smoke-pipe C, more or less, and thus the draught can be regulated at will.

I am aware thatthe solid cap in the iower part of the sad-iron has been before known and used, but, as it E I claim as new, and desire to secure by Letters Patent- V 1. The cover D, constructed as described, consisting of the plates 6 a,- forming a eold 'air chamber, the upper plate being slotted for the passage of the arm e of the catch-damper as herein shown and described.

has the tendency to heat the top of the iron instead ofthe bottom, I do, not, therefore, claim it; but" 2. The adjustable sliding damper G, when arranged below or near the mouth ofhthe-smoke-plpe C of a. hollow self-heating smoothing-iron, substantially as and for the purpose herein shown and described.

3. A self-heating smoothing-iron, when "provided with a. perfoyated cap fixed in the interior of the hollow iron, with a double cover, D, and with an a-djustable damper, G, all made and operating suh stnntially as and for the purpose herein shown and deseribed.
